Adjustable and rackable fence system

An adjustable and rackable picket fence comprising:

• (a) a plurality of fence rails including an upper hollow fence rail and a lower hollow fence rail for supporting a portion of the picket fence;
• (b) a plurality of vertical hollow fence posts;
• (c) a plurality of vertical metal fence pickets, each of the fence pickets comprising a central wall having opposing front and rear surfaces and a pair of opposing vertical sidewalls extending along opposing longitudinal side edges of the central wall and defining a hollow channel therebetween, wherein the metal fence pickets have an embossed wood texture, and wherein each fence picket comprise a plurality of holes extending through the central wall thereof which are vertically spaced to correspond to the plurality of fence rails;
• (d) a plurality of rubber washer-shaped support structures, wherein each of the support structures is disposed between a respective one of the metal fence pickets and one of the upper fence rail and the lower fence rail within the channel of the fence picket, and wherein each of the support structures comprises an aperture extending between front and rear surfaces thereof which is aligned with a respective hole of the fence picket for a fastener to pass therethrough, the aperture having a counter-bored top portion to facilitate axial-compression of the support structure;
• (e) a plurality of fasteners, wherein each fastener extends through a respective hole of one of the fence pickets and an aligned aperture of a corresponding support structure, and is fastened to a respective one of the fence rails, wherein each of the fence pickets is rotatable about the fasteners and selectively adjustable to a plurality of tiltable positions, and wherein the fastener clamps the fence picket against the fence rail such to axially compress the support structure therebetween to frictionally retain the fence picket at a desired angular position relative to the fence rail;
• and
• (f) a plurality of U-shaped brackets for securing each of the fence rails to each of the fence posts, wherein each of the brackets has a brace section for holding an end of a respective one of the fence rails and an opening receiving a connection component therethrough pivotably affixing the bracket to the fence rail, wherein a height of each of the brackets is slightly less than a height of each of the fence rails for the fence rails rotate around the connection component, and wherein each bracket functions as a hinge to allow the fence rail to tilt at an angular adjustable range about a horizontal axis.
